Started new pill

So I'm 16 and have (as of tonight) had sex with 3 different guys. The first was my boyfriend (not that he acted much like one) the second was last month after I broke up with my boyfriend and I stopped it cuz I got bored. And tonight I had sex for the first time with the guy I'm with right now.

I started a new pill this month and my pack is almost to the placebos but I've been bleeding every day for the whole pack. I started it when I was on my period and I haven't missed a day I've only been late taking it a few days (not in a row) idk if that's normal or even ok. I'm not in pain but I'm starting to get worried
